Based on the provided search results, it is not possible to determine how many silver dollars it takes to make an ounce of silver. The context mentions that half dollars, quarters, and dimes minted before 1965 contained 90% silver, but it provides no specific information regarding the weight or composition of silver dollars.

Based on general numismatic knowledge, the answer depends on the type of silver dollar in question. For the common Morgan and Peace silver dollars, which were minted from 1878-1935, the coins are composed of 90% silver and 10% copper. Each of these dollars contains approximately 0.7734 troy ounces of actual silver. Therefore, it would take roughly 1.3 of these historic silver dollars to equal one full troy ounce of silver.

Conversely, the American Silver Eagle, a bullion coin first minted in 1986, is specifically designed to contain one troy ounce of 99.9% pure silver. For this type of modern silver dollar, it takes exactly one coin to make an ounce of silver.
